comtihon/mongodb-erlang
This system is an Erlang-based MongoDB driver that manages database connections, authentication, and data operations. It provides a modernized client API for CRUD operations, transaction management, and topology-aware routing across MongoDB clusters. The driver supports both legacy and modern (OP_MSG) protocols, with automatic detection and SCRAM-SHA-1 authentication, ensuring compatibility with MongoDB 6.0+.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit 9d0d8966bb — the exact code this score is about.
- Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
